What problem does this PR solve?
Issue Number: ref #43559
Problem Summary:
This PR implements the new (hidden) command "br operator pause-gc", which blocks the shell and then pause the global GC safepoint.
There are two flags for this command:
--safepoint
or-t
, the GC safepoint to be kept, default current resolved ts.--ttl
or-i
, how long the service safe point lives, default 5 mins.What is changed and how it works?
This PR just reused the
StartServiceGcSafePointKeeper
.Check List
Tests
(It is not easy to auto test this PR.)
Firstly, we paused the safepoint.
The metrics shows that the safepoint has been kept.
This test also applies to the schedulers.
